Study Notes

Arteries and Veins Classification

Some arteries exhibit characteristics that blur the lines between different types, complicating classification.
Examples include superior and inferior vena cava as well as the hepatic portal vein.
Large veins typically have diameters greater than 10 mm, indicating their significant size.

Blood Cells

Blood cells include red blood cells (RBCs), also referred to as erythrocytes.

Leukocytes (White Blood Cells - WBCs)

Leukocytes are categorized into two primary groups based on the presence of specific granules in their cytoplasm.
Granulocytes:
- Contain specific granules in their cytoplasm.
- Include neutrophils, eosinophils, and basophils.
Agranulocytes:
- Lack specific granules.
- Comprised of lymphocytes and monocytes.
Neutrophils are the most abundant white blood cells and represent the most common type of granulocyte.
Neutrophils measure between 10 to 12 micrometers (µm) in diameter and are larger than RBCs.

Thrombocytes (Platelets)

Thrombocytes originate from large polyploid cells called megakaryocytes in the bone marrow.
Megakaryocytes contain multiple sets of chromosomes, allowing for the production of numerous platelets.
